I don't think so. It only affects things early in boot (before efi_enter_virtual_mode()) is called. Once we've called SetVirtualAddressMap() we call virt_efi_get_time() to get the time and everything works fine.
I don't think this bug is even visible to the user apart from the "Oops: efitime: can't read time!" message displayed on boot. It certainly doesn't cause a crash or anything like that.
